Etymology: Longitudinally is a plain formation: the adverb "-ly" added to "longitudinal," which itself comes from Latin "longitudo," meaning length, from "longus," long. The Latin root has passed into English as a technical term for measurement along the long axis of something, such as a ship, a bone, or a crystal. The adverbial ending has a longer history than the word's Latin core. The suffix descends from Proto-Germanic "-līkō," a word that meant something like "body" or "form" and gave rise to the idea of "having the appearance of." Over centuries this developed into the Old English "-līċe" and then the Middle English "-ly," which English now attaches to countless adjectives to make adverbs of manner. The same ending turns "quick" into "quickly" and "brave" into "bravely."
